Impacted corticocancellous allografts and cement for femoral revision of total hip arthroplasty using Lubinus and Charnley prostheses.

摘要

Femoral revision of total hip arthroplasty using impacted morcellized allografts and a cemented Lubinus SP-II prosthesis (Waldemar Link GmbH & Co, Hamburg, Germany) or Charnley standard prosthesis (De Puy, Leeds, UK) was performed in patients with loss of bone stock grade II-IV according to the Endoclinic classification from first to eighth revision. We report the results from 57 hips in 56 patients, with a median of 64 months' follow-up. Modified Merle d'Aubigne-Postel postoperative scores increased significantly from preoperative to postoperative values for the Lubinus group and for the Charnley group. Few complications were seen in this follow-up period. Five stems had minor subsidence. Mechanical failures were 4% for both groups. Radiologic examinations provided evidence of frequent trabecular remodeling of the graft, especially for the Lubinus prosthesis.
